Hi @sperlingxx! Thank you for adding validations 👍 I put some review comments.
| __schema_dict = { | ||
| 'tpe': { | ||
| 'gamma': (lambda x: float(x), lambda x: 1 > float(x) > 0), | ||
| 'prior_weight': (lambda x: float(x), lambda x: float(x) > 0), | ||
| 'n_EI_candidates': (lambda x: int(x), | ||
| lambda x: float(x).is_integer() and int(x) > 0), | ||
| "random_state": (lambda x: int(x), lambda x: x.isdigit()), | ||
| }, | ||
| "random": { | ||
| "random_state": (lambda x: int(x), lambda x: x.isdigit()) | ||
| } | ||

I mind that validate functions ( __schema_dict[algo_name][s.name][1] ) cannot return the message why parameters are invalid.

And I personally feels this dict is a bit tricky. I prefer the following code:
@classmethod
def _validate_tpe_setting(algorithm_settings):
for s in algorithm_settings:
if s == 'gamma' and 0 < float(x) < 1:
return False, "gamma should be in the range of [0, 1]"
...
return True, ""
@classmethod
def validate_algorithm_spec(cls, algorithm_spec):
algo_name = algorithm_spec.algorithm_name
if algo_name == "tpe":
return cls._validate_tpe_setting(algorithm_spec.algorithm_setting)
elif algo_name == "random":
return cls._validate_random_setting(algorithm_spec.algorithm_setting)
return False, "invalid algorithm name"But I want to hear opinions of maintainers ( @andreyvelich @gaocegege ).

I'm okay with both code styles.

I agree with @c-bata, I think for validation we should say why settings is not correct. Like we did with enas: https://github.com/kubeflow/katib/blob/master/pkg/suggestion/v1alpha3/nas/enas_service.py#L218

@c-bata @andreyvelich I've refactored codes of validation part.

[nits] I guess you can remove redundant brackets. It's OK to ignore this comment.
